您好,最近我们团队在做一些与责任链相关的coding,拜读了您的源码,深受启发,感谢!
DefaultKeyIdentificationChain.java在匹配对应的KeyIdentification时:
List<KeyIdentification> identifications = identifyMap.get(workflowId);
if(identifyIndexMap.containsKey(workflowId)) {
index = identifyIndexMap.get(workflowId) == null ? 0 : identifyIndexMap.get(workflowId);
} else {
index = 0;
}
if(index == identifications.size()) return IdentificationResultType.NO_MATCH;
KeyIdentification keyIdentification = identifications.get(index);
index ++;
identifyIndexMap.put(workflowId,index);
return keyIdentification.doIdentify(identifyCriterion,this);
当多个线程同时进行doIdentify()时,线程之间的index++是否会受到干扰?望指教!我们目前在这个地方使用ThreadLocal处理,是否有这个必要?
期待mybatis
